opcenter8 使用webapi+Angular.js+bootstrap 开发

opcenter8的开发方式跟之前的camstar7版本差不多，自带的UI开发上手难度大，调试困难，开发周期变得很长，所以此文章再不添加任何第三方插件的情况下使用系统自带的Angular.js+bootstrap做开发

1.添加WEBAPI支持

添加WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API 配置和服务

        // Web API 路由
        config.MapHttpAttributeRoutes();
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

　　在Global.asax的Application_Start方法添加代码

System.Web.Http.GlobalConfiguration.Configure(WebApiConfig.Register);

　　在Global.asax的Application_BeginRequest方法添加代码，设置在webapi中使用session

 HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);

　　在webconfig的runtime节点添加json依赖

<dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" culture="neutral" publicKeyToken="30ad4fe6b2a6aeed" />
        <bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
      </dependentAssembly>

　　添加控制器ValuesController.cs

public class ValuesController : ApiController
{
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }
}

在浏览器界面上调用 https://localhost/CamstarPortal/api/values

2.添加前端界面和菜单

自定义界面
添加页面在主目录下添加文件夹html,再添加自定义页面demo.aspx

添加菜单

这个时候点击菜单页面并不会显示出来，修改PortalService.cs的GetChildMenuItems方法，添加三行代码（黄色底色部分）

private ApolloMenuItem[] GetChildMenuItems(string parentName, Row[] menuItems)
        {
            var resultMenuItems = new List<ApolloMenuItem>();
            if (string.IsNullOrEmpty(parentName))
                return resultMenuItems.ToArray();
            var session = FrameworkManagerUtil.GetFrameworkSession();
            var items = menuItems.Where(i => i.Values[11] == parentName).ToArray();
            foreach (var item in items)
            {
                var pageFlowName = item.Values[7];
                var virtualPageName = item.Values[9];
                var url = item.Values[3];//添加的代码1
                var navigateToUrl = (!string.IsNullOrEmpty(virtualPageName) ? virtualPageName : pageFlowName);
                navigateToUrl = string.IsNullOrEmpty(navigateToUrl) ? url : navigateToUrl;//添加的代码2
                pageFlowName = !string.IsNullOrEmpty(url) ? item.Values[1] : pageFlowName;//添加的代码3
                 var queryString = string.Empty;
                if (item.Values[4] != null)
                {
                    queryString += item.Values[4].ToString();
                }
                if (item.Values[5] != null)
                {
                    queryString += queryString.EndsWith("&") ? "" : "&";
                    queryString += "ServiceName=" + item.Values[5];
                }


                var newItem = new ApolloMenuItem()
                {
                    Id = item.Values[0],
                    DisplayName = item.Values[1],
                    DisplayValue = item.Values[2],
                    QueryString = queryString,
                    UIPageFlowName = item.Values[7],
                    UIVirtualPageName = navigateToUrl,
                    ParentName = item.Values[11],
                    Order = item.Values[16],
                    ApolloIcon = item.Values[17]
                };
                var children = this.GetChildMenuItems(newItem.DisplayValue, menuItems);
                if (children != null)
                    newItem.Children = children;
                if (string.IsNullOrEmpty(newItem.UIVirtualPageName) || session.GetAuthorizationManager().IsUIComponentAuthorized(newItem.UIVirtualPageName) || !string.IsNullOrEmpty(pageFlowName))
                {
                    resultMenuItems.Add(newItem);
                }
            }

            // Set home page
            var homePage = session.SessionValues.UserPortalProfile.PortalV8HomePage;
            var rootMenuName = session.SessionValues.UserPortalV8MenuName;
            var homePageLbl = FrameworkManagerUtil.GetLabelValue(_homePageLbl) ?? "Home Page";
            if (!string.IsNullOrEmpty(homePage))
            {
                var homeMenuItem = resultMenuItems.FirstOrDefault(hmi => hmi.UIVirtualPageName == homePage) ?? null;
                if (homeMenuItem != null)
                {
                    homeMenuItem.IsHomePage = true;
                    homeMenuItem.DisplayValue = homePageLbl;
                }
                else if (resultMenuItems != null && parentName == rootMenuName) // add home menu item if configured and parent is root and not included in menu items
                {
                    resultMenuItems.Add(new ApolloMenuItem
                    {
                        UIVirtualPageName = homePage,
                        DisplayName = homePageLbl,
                        DisplayValue = homePageLbl,
                        Children = new ApolloMenuItem[0],
                        ParentName = rootMenuName,
                        IsHomePage = true
                    });
                }
            }

            return resultMenuItems.ToArray();
        }

　修改demo.aspx内容

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="../Themes/Horizon/bootstrap.min.css" rel="stylesheet">

</head>

<body>

    <div ng-app="myapp" ng-controller="AppCtrl">
        <div class="input-group mb-3">
            <div class="input-group-prepend">
                <span class="input-group-text" id="basic-addon1">@</span>
            </div>
            <input type="text" class="form-control" placeholder="Username" aria-label="Username"
                aria-describedby="basic-addon1" ng-model="name">
        </div>

        <div class="input-group mb-3">
            <input type="text" class="form-control" placeholder="Recipient‘s username" aria-label="Recipient‘s username"
                aria-describedby="basic-addon2" ng-model="name">
            <div class="input-group-append">
                <span class="input-group-text" id="basic-addon2">@example.com</span>
            </div>
        </div>
        <button type="button" class="btn btn-success" ng-click=‘say()‘>Success</button>
    </div>

    <script type="text/javascript" src="../Scripts/jquery/jquery.min.js"></script>
    <script type="text/javascript" src="../Scripts/jquery/bootstrap/bootstrap.bundle.min.js"></script>
    <script type="text/javascript" src="../assets/lib/angular/angular.min.js"></script>
    <script type="text/javascript">
        var app = angular.module(‘myapp‘, []).controller("AppCtrl", function ($scope, $http) {
            $http({
                method: ‘GET‘,
                url: ‘../api/values‘
            }).then(function successCallback(response) {
                // 请求成功执行代码
            }, function errorCallback(response) {
                // 请求失败执行代码
            });
            $scope.name = "fff"
            $scope.say = function () {
                alert($scope.name)
            }

        });
    </script>
</body>

</html>

　这个时候再去点击菜单，页面就显示内容出来了，同样道理如果喜欢其他前端框架的可以自己加到项目里。
